We could not cope on camps without audiology, we usually have two or three expatriate audiologists on the camp with us. Two of our Nepali staff have some knowledge and can do basic audiology and hearing aid fitting. We carry 2-3 small battery powered diagnostic audiometers and 1-2 tympanometers. The work is very busy; on a recent camp the audiologists did well over 300 PTAs and fitted over 130 aids. The aids are fitted using a single stage soft mould or ready made/universal moulds. We are constantly in need of aids to supplement our supplies, especially analogue aids. We often see people with profound hearing loss some of whom are also dumb, they often develop local types of sign language. We sometimes see people with congenital problems like atresia, so bone hearing aids can be useful. (See Jemima and Bridget's Audiology Tips)Audiology Language Sheet
